P/V valve with force closed device
it can ensure the "zero leakage" after assemble the forced-closing device on the CF-ISO high-velocity relief valve
The pressure valve will automatically open when the pressure in the tank reaches to the set pressure of the high-velocity relief valve and the gas in the tank will be released with the speed of 30m/s once assemble the high-velocity relief valve on the ventilation system of the cargo oil tank, A manual ventilation system gas-freeing cover is necessary while do other works of the tank such as cleaning, removing the gas, because such works need ventilate and the pressure valve cannot work while the pressure is low or without pressure (remark: The pressure valve is not manual and it will work with the velocity of smaller than 30m/s).
Shell, upper cover and flame screen (flame retardant bed) constitute gas-freeing cover. It can directly assemble on the vacuum valve of the high-velocity relief valve.
